AIDS symtoms essays

AIDS symtoms essays The symptoms of AIDS are primarily the result of infections that do not normally develop in people with healthy immune systems. These infections are termed "opportunistic infections." Patients with AIDS have had their immune system destroyed by HIV and are susceptible to such opportunistic infections. The general symptoms are fevers, sweats, chills, weakness, and weight loss. Some other ones are loss of energy, weight loss, a thick, whitish coating of the tongue or mouth that is caused by a yeast infection and sometimes accompanied by a sore throat. There is also an easier chance of bruising, a continuos deep dry cough, and an increase in loss of breathe. These symptoms however may not necessarily mean that you have AIDS. The best way to fully be sure that you have AIDS would be to go see a doctor. It may just be that you have a very bad cold. Yet people normally will have HIV for years before they fully develop AIDS at which point they should be aware of it. There are however for main stages of HIV/AIDS. This is how people normally develop AIDS: This is when people first contract HIV/AIDS. This stage may last about three (3) months and in some rare cases, as long as a year. Now a process to produce anti-bodies symptoms of infection. This stage may last for years. At this stage, people show signs and symptoms of infection. This stage may last for years as well. Immune system cells are severely depleted. Now the body enters full blown AIDS. At this point the bodys Immune System is completely destroyed. So now more diseases easily spread to the victim. However children get more symptoms which are also complications within them selves. Some of these symptoms are: ...

Free Essays on Movement Into Pleistocene Era

The current 65 million year long Cenozoic Era is divided into the five epoch Tertiary Period and the present Quartenary consisting of the recent 10,000 year Postglacial and the Pleistocene epochs. The latter is characterized by extreme alterations in climate that placed intense survival pressures on hominids. Behavioral flexibility was survival selected by abrupt, extreme ecological changes. During this period Homo erectus migrated out of Africa with a most important ability, the knowldge of fire. In Europe and the Middle East Homo sapiens, also know as Neanderthals, evolved. A short stocky hominid of powerful physique with prominent brow ridges, a sharply sloped back forehead and a cranial capacity greater than modern humans, Neanderthals were well adapted to the temperate to arctic zone they occupied.

Strengths, Weaknesses and Strategies for Sugar Bowl Essay

Strengths, Weaknesses and Strategies for Sugar Bowl - Essay Example Sugar Bowl can effectively take maximum advantage of this student presence in order to increase their visitation to the business especially on some of the slow nights (Hamermesh and Zalosh, 9). Additionally, it is important to realize that since its opening, Sugar Bowl has been experiencing slow growth, having been in the industry for only one year; generally, restaurants and bars often take close to five years in experiencing solvency. Sugar Bowl boasts of a good target market that comprises of many graduate students and young professionals who will enhance its growth and success. Some of the goals regarding the operations of Sugar Bowl include an inability to retain some of its competent sales staff. This means that the company is often left with the option of having its unused capacity being supplemented by other outside workers. Additionally, the company has a problem with compensating its staff in order to elicit maximum support from them. In improving the compensation criteria, the company can be in a better position to enhance their staff morale while reducing the high turnover that it faces. Additionally, the company has high training costs and theft cases, which are said to be emerging from within. Through such activities as effective staff training and motivation, the company will enhance its success and performance, something that will aid in its achievement of goals and objectives. Through effective staff empowerment initiatives, Sugar Bowl will experience reduced daily operations for its management teams (Hamermesh and Zalosh, 10). The company’s inability to predict its sales revenue in the most effective way has also been a major weakness in its growth prospects. Some of the opportunities that Sugar Bowl is facing in its growth and success are largely depended on the need to capture new markets presented by the target marketing, who are students and other young people generated by the universities available in this area.

HRM methods Essay Example | Topics and Well Written Essays - 3750 words

HRM methods - Essay Example This is nothing but performance-based compensation, which is one of the widely acknowledged HRM practices that contribute to business success (Dyer & Reeves, 1995; NC-DHHS, 2005). The employees' knowledge that such a reward awaits them if they perform well should keep them on their toes. Granting pay incentives and job promotions according to seniority and length of stay, which is the usual practice, does not motivate employees across the organization because the newer employees know that they will receive the same benefits and career boosts if they just stayed longer in the company and all they need to do is wait for their turn. While they thus wait for their time, you cannot expect them to exert themselves harder at their jobs. Even with a so-so performance, they tend to feel secure in their positions because of employment laws or labor union agreements that forbid dismissal without cause. With the forced ranking and distribution system in place, employees will strive to avoid bein g included in the worst performing group. ... The downside of the system, however, is the perceived lack of a foolproof benchmarking method to measure performance. As noted in the case study, it is inherently difficult to differentiate between good, average and poor performance. Precisely because of this particular difficulty, Goodyear mistakenly fired one chemist who got a consecutive C ranking for poor performance but who, it turned out, had earlier patented a new type of aircraft tire without management knowing about it. In essence, the forced ranking and distribution system is an anachronism to the popular HRM model that sees companies setting up rigid screening processes to ensure that they hire only the best people (Storey, 1992; Guest, 1999). If these companies hire only the best, then how come there are poor performers to be found in their ranks Dow Chemical, for example, realized in time that the forced ranking system did not fit with its corporate philosophy of recruiting only the best employees. In addition, the forced ranking system is likely to provoke perceptions of status and discrimination, thus encouraging income comparisons and perhaps spreading envy as others see a fellow employee doing much better than them (Guest, 1999). Envy and jealousy could have prompted employees at Ford and Goodyear to complain that the system discriminated against certain type of employees. 2) Suppose any of Ford, Goodyear and Dow Chemical contacts you to modify its performance management system to avoid some of the problems that it has experienced. What would you suggest the company do If asked to suggest a performance management system that avoids the pitfalls of the forced ranking and distribution system, I would propose a system that emphasizes the

Scientific Management Theory Analysis

Scientific Management Theory Analysis The emphasis on increasing productivity from individual worker impels the emergence of F. W. Taylors scientific management at the beginning of 20th century. His philosophy of rationalizing work and organization to achieve maximum productivity, cooperation and prosperity has influenced the production and management model of his age profoundly. Despite the past 100 years, the shadow of Taylors philosophy in terms of production approach and management practice is still alive at the times of information technology, flexibility of production and the industrial restructuring. As Stern has written, The scientific management of Fredrick Taylor shaped the first coherent school of thought with its twin goal of productivity and efficiency- still influences management thinking 100 years on. This essay will assess the influence of scientific management on contemporary organization. Before assessing the influence, it is also important to introduce what scientific management is. It is a set of systematic theory of the correlation between labour and tasks for the purpose of increasing productivity by redesigning the work process. Based on the famous time-motion-study, Taylor developed four principles to increase efficiency: Study the way workers perform their tasks, develop a science for each element of a mans work, which replaces the old rule- of-thumb method. Codify the new methods of performing tasks into written rules and standard operating procedures Carefully select workers who posses skills and abilities that match the needs of the task, and train them to perform the task according to the established rules and procedures Establish a fair or acceptable level of performance for a task, and then develop a pay system that provide a reward for performance above the acceptable level Scientific management is a complete and interrelated system, but this essay will examine Taylors four principle separately to simply the analysis. One best way and division of labour Generally, Taylor believes that there is a one best way of each task to achieve maximum productivity and during his age, He firmly believes the division of labour is the best way to achieve this. Though nowadays, due to the diversification of the market and the organization, the simple one best way can hardly be defined, such as business adopt mass-production strategy can have a completely different optimal method of production than those focus on niche marketing, his spirit of pursuing the best way is still vivid presented. Just as the quality circle pioneered by Japanese car manufacturing, modification is being discussed continuously to make the work process more streamlined, more efficient and not wasteful in its activity, which is essentially the goal of Taylors system.(Stoney, 2001:p27) Especially when information technology has become the means of analyzing the underlying flow of material and information, it is more convenient and prevalent for contemporary organization to deci de the best redesign of business process to pursuing productivity, quality and competitive posture. Incorporated in his spirit, division of labour is the specific outcome of scientific management, the best way Taylor advocates to minimize skills required, and assembly-line, the creation of his age, are also still utilized successfully in contemporary fast-food industry. Such as MacDonald, the unskilled tasks from broken-down cooking procedure and sophisticated time record make it a completely modern duplication of Taylorism. The assembly lined production mode underpins the repetitive work cycle on the line by setting standard times. By doing this, efficiency improves dramatically as unnecessary tasks are eliminated, physical layouts improved, and work speeded up. (Fincham Rhodes, 2005: p678) Despite that deskilling () will de-motivate employees significantly on a general scale, which may result in absenteeism and high staff turnover, its ability of integrating new workers in production processes and dismissing workers without losing knowledge form the organization can successfully overcome it. Besides, the emphasis on quantity rather than quality (Ritzer, 2004) of the fast food industry also highlights the need of efficiency. Taylors influence goes beyond the bounds of manufacturing, the growing army of clerks in the rising service sector are automatically divided into departments and specialized in function. (Fincham Rhodes, 2005: p608) This means the philosophy of division of labour apply to most clerical works to rationalize the working procedure. A merging characteristics of clerical and production labour () becomes one remarkable feature of modern society. However, the anomie and alienation brought by the absolute division of labour limit its further application. The knock-on effect of de-motivate employees on quality and service can have more significant negative impact on contemporary organization than ever when they become the key to profitability at modern times. Despite the limitation of his method, this principle has a considerable profound and lasting influence because of Taylors preoccupation with the efficient use of resources. This philosophy can almost apply to every organization because whichever the work structure is taken, such as the prevalent team work and job enrichment; one of its ultimate goals should be improve efficiency. It can be proved by xxs argument that ()quality circles, rather than being a transformation of labor relations toward democratic participation, are managerial strategy to facilitate workers cooperation with managements goals for efficiency and productivity improvements. Standardization and direct control Taylor proposes standard rules to capture the best practice and direct control of workers to maintain efficiency. As Braverman (1974, p. 47) recognised, Taylorism never was a science, but a control system. Due to separate conception and execution, managers should design, allocate tasks and supervise workers performance without consulting employees opinions.(McGeorge Thoery X) Actually the appliance of Taylors efficiency through rationalization (Stoney, 2001: p.27) builds a mechanistic organizations, with strict rules, standardized defined tasks and top-down communication. Contemporarily, there are still cases where mechanistic organization proves to be optimal. A classic example is call centre where standard script must be followed, number of calls per hour is strictly monitored, as well as managers can listen in calls momentarily. Though it is argued that this complete control will alienate employees as it erodes the sense of freedom and self-determination, only this mechanic struct ure, where all tasks are designed to be consistent and coordinated, rigid rules are followed and instructions are obeyed immediately, can achieve the speedy service and uniform quality. Besides, despite its formalized and hierarchy nature causes inflexibility, organizations, such as call centre, which exist in a relatively stable environment where not much innovation and adjustment are required, has proved to be more effective because of the systematically rationalize procedures. (Burns Stalker, 1961) Thus, it still exists where efficiency dominates effectiveness. More commonly, only element of direct control can be seen in most contemporary organization. For instance, in public accounting firms, supervisor accountants supervise lower-rank accountants assigned with them to each audit. Junior accountants should work under the direct guidance of a senior accountant.(Hall, 1968) This is still due to Taylors inherent advantage, direct control can boost efficiency by rationalizing complex accounting procedure and adopting tasks efficiently and accurately. A further reason is that when meticulousness it the first requirement and errors may cause serious consequence, it is direct control that can maintain efficiency at the same time safeguard the quality. Efficient as it is, the reasons for not being fully adopted is that the drawbacks of direct control largely limit its influence. As Friedman (1977) points out, it neglects the positive aspects of labour. That means know-how and practical experience cannot be reflected and diffused. And the formalized system develops passive organization culture which undermines innovation, commitment and flexibility. This contradicts to the requirement of contemporary organization, especially for manufacturing. At modern times, in manufacturing sphere, the key to profitability lies in innovation.(Ackroyd, 2002) It means how to improve application for existing technology, how to create market advantage by good design and exclusivity become the very crucial issues. This is why most of contemporary organizations only retain elements of direct control and tend to be decentralized to emphases on democratic participation. To a broader extent, Taylors standardization philosophy is more widely used, and the new globalized era makes it an urgent requirement for business. Due to the great advantage of diffuse best practice, standardization becomes the key to facilitate the diffusion of businesss know-how to a new area for achieving a competitive advantage. Meanwhile, it is necessary for coordinating activities on a world wide scale and maintaining strict quality to safeguard firms reputation. However, exposed to a greater level of external complexity, the drawback of rigidity brought by standardization must be overcome, thus standardization is a continuous improvement process nowadays, just as the standard operation in Japanese car manufacturing where work is performed according to standard work sequence to insure quality, meanwhile standard if frequently updated to standardize improvement.(Edwards et al, 1993) To achieve this, standardization tends to be combined with a flatter and organic organization s tructure highlighting integration and decentralization to keep innovative and flexible. Scientific selection and training This is perhaps the most relevant principle today because these processes, selection, performance, as well as appraisal and development have been highly formalized in many organizations today (Cole, 2004). In the knowledge-based economy, talent has become the very valuable asset of business to achieve competitiveness. Much effort is devoted by contemporary organizations on selecting the right person. The contribution of Taylor is that he introduced the importance of selection criteria by management, such as the common competencies (i.e. communication skill, initiative) listed by recruitment department. In line with his emphasis on scientific approach to selection, Taylor advocates scientific training as he argues that it is only when business systematically cooperating to train the competent manà ¢Ã¢â€š ¬Ã‚ ¦that it shall be on the road to national efficiency. (Taylor, 1911: p 98)In the context of the knowledge society, companies are generally encouraged to develop employees skills and knowledge (Hansson, 2007) Such as Nissan UK believes the key way for being the most productive car plant in Europe is its ambitious training scheme involving its entire manufacturing workforce.(Lydon, 2007) Costly as it seems, the long-term benefits of quality, safety performance and manufacturing costs overweight it. Moreover, training is usually positively related to promotion (Bayo-Moriones OrtÄ ±Ãƒâ€šÃ‚ ´n-Angel 2006) it means it can motivate employees by satisfying their growth, achievement needs. Overstepping Taylors efficiency idea, nowadays the meaning of training is also related to be flexible and acuity enough for competing in a more complex global market, such as the widely-used management trainee schemes in multinationals to cultivate managers with practical experience and global perspective. Money as a motivator Taylor advocates piece-rate payment scheme based on his assumption that human nature is essentially self-interest, workers would be motivated by obtaining the highest possible wage by working in the most efficient and productive way. (Mullins, 2001: p23) In modern age, despite his method can rarely be seen due to the decadence of manufacturing, Based on his philosophy, money motivation still play a crucial role in other form, such as the incentive-based pay system. One common example is sales bonus. The rush of a sales force to place orders before month end reflects highly targeted performance. Thus there is little doubt that this system will work if designed appropriately. In the new context, when various approaches (i.e. job enrichment, team work) are applied to improve personal commitment, money motivator is not narrowed for efficiency as well. For instance, bonuses assessed on cooperation can represent up to 50% of wage packet in Japanese system and group bonuses are also given. (cf. Dohse et al., 1985, pp. 137-8) It means money motivator is now used flexibly according to organizations strategy. Ryness study of pay motivation in contemporary organization also support Taylors assumption, as there is overwhelming evidence that money is an important motivator for most people. Furthermore, he found that for high academic achievers, high performing employees and individuals with high self-efficiency and high needs for achievement, pay are the most important motivator.(Rynes et al, 2004) It means nowadays pay maybe more crucial than ever as those kinds of person are just the valuable human resources that organizations compete for. However, it is undoubted that Taylors idea of motivation is narrow minded and not suit as an extrinsic motivator, the emphasis on money will decrease staffs intrinsic motivator. Despite that, contemporary organizations usually adopt compromising approach as nowadays, the satisfaction of social needs and achievement needs are regarded as almost equality important motivator. Thus, multiple motivators, money in conjunction with other intrinsic motivator are more prevalent. For instance, performance-based pay and challenging work are used in such successful firms as Microsoft. Conclusion remark It should be admitted that there is almost no other management theory can overstep the influence of scientific management. As Braverman says, the principle of scientific management is not a failed system, but a set of guiding principles which continue to inform and influence the role and function of modern management. Some of the methods he advocates, such as division of labour, scientific selection and training, have become the features of modern society. More primarily, as efficiency is one of the enduring needs of all organizations, his preoccupation with the efficient use of resources thus becomes the driving force behind the evolution of subsequent management theories () and the root of management practice. Due to its extensive and deep influence, it is institutionalized not only in contemporary corporation, but also ideologically embraced in other institutions, modelling the modern world with the character of efficiency, calculability, predictability and control through technol ogy. (Ritzer) However, its inherent drawbacks of inflexibility, dehumanization require modification in current situation. Therefore, it can be argued that management of contemporary organization is based on a modification of Taylorism and a combination with more sophisticated management theories.

Warfare :: Essays Papers

Warfare Warfare is a prominent theme in Beowulf . The reasons and conduct for and during warfare are mentioned and displayed throughout the poem. The reason for warfare is usually for retribution. As an act of revenge, battles are fought. The conduct is also very standard and prevalent. All warfare fought by honorable men had to be fought fair. If the opposing side bore no weapons, then the other side also used no weapons. The author of this poem depicts himself/herself to be an advocate of warfare. By idolizing Beowulf because of his heroic deeds during warfare, the poet makes armed conflict courageous and noble. The reasons for bloodshed are spelled out quite well when noble Beowulf consoles his sad friend, Hrothgar concerning his friends demise. He tells him: " Sorrow not wise warrior. It is better for a man to avenge his friend than much to mourn" (Norton 45). Beowulf advocates and promises to avenge Aeschere’s death during warfare with the slayer, Grendel’s mother. The act of battle is given a reason and purpose which is to avenge a death. Conduct in warfare might be "every man for himself" in today’s world however, during Beowulf’s time, the poet shows that honor was the most valuable asset. Upon knowledge that Grendel used no weapons, just bare flesh, Beowulf immediately put his weapons aside and promised to fight empty handed, so the fight would be fair. "I have also heard say that the monster in his recklessness cares not for weapons......I scorn to bear sword or broad shield, yellow wood, to the battle, but with my grasp I shall grapple with the enemy and fight for life, foe against foe " (Norton 32). An unfair fight, as the poet implies, has no glory or distinction. This proves Beowulf to be a worthy hero and role-model. The poet gives the impression that warfare is honorable and exciting. This does not imply that the poet likes bloodshed; it refers to honorable warfare. Honorable warfare includes a good reason and virtuous conduct. The poet can not be a pacifist because he/she describes Beowulf as a savior and hero. If the poet was a pacifist he/she would have described him as an egotistical bully. The poet makes Beowulf an icon and noble warrior. Beowulf is described as " †¦survived every combat, every dangerous battle, every deed of courage†¦" also called ".

Effect of Light Color on Plants

Introduction Living organisms have been classified by humans according to several different characteristics, one of them being the manner in which they obtain nutritive organic molecules (1), in other words, their food. Plants are denominated as autotrophs, organisms that can produce their own food from abiotic sources surrounding them, such as light, carbon dioxide and water (2). Plants use these three factors in photosynthesis to convert light energy into chemical energy, which is then stored until the plant needs it, or used right away (3). The process of photosynthesis takes place on organelles (substructures inside eukaryotic cells) called chloroplasts, more specifically, on the membrane of the thylakoids inside the chloroplasts, where protein complexes known as photosystems are situated. It’s these complexes that are responsible for the photosynthetic processes. Because this is the main way in which plants obtain their food, and light energy is the base of said process, light is absolutely essential for their growth. Sunlight contains many different wavelengths which, when isolated, present different colors of visible light. Plants cannot use all wavelengths of light, however, because the different chlorophylls (pigments in the plants’ chloroplasts, also responsible for photosynthesis) absorb and use only certain wavelengths of light ; the rest is reflected back out, unused (4). Exposed to sunlight, plants have available to them, a range of wavelengths wider than the light spectrum visible to us, from which they utilize only a select range for photosynthesizing. This essay will investigate the effect light color/wavelength has on plant germination and rate of photosynthesis. Cellophane sheets of different colors (red, yellow, blue, green) and clear plastic wrap were used to provide these limited wavelengths . The experiments dealing with germination consisted of different seeds being planted separately from other species and being covered by the different colored cellophane or the clear wrap; they were then watered and monitored for a week, taking note of any growth. The plants used were the common bean (Phaseolus vulgaris), brown mustard (Brassica juncea), and common oats (Avena sativa). For the photosynthesis rate experiment, same sized Brazilian waterweeds (Egeria densa) were inserted in eudiometer tubes filled with water and then placed in a beaker half-filled with water. Each test tube was wrapped with a different color, and the volume of oxygen produced, through photosynthesis, by each of the plants was compared. Beans, specifically all the plants under the genus Phaseolus, are amongst the fastest growing plants and are said to germinate within a week. To make them germinate faster, it’s usually recommended to soak them in water before planting because hydrating the seeds stimulates germination. (5) They also benefit from warm temperatures because they are native to more tropical climates (6). They need to be planted in well drained soil because they aren’t tolerant to water excess. Mustard is also among the fastest sprouting plants, but its growth afterwards is relatively slow as it’s meant to grow flower buds five weeks later. It does better in cool conditions than warm and can usually withstand short periods of mild drought with little to now consequences. In addition, it too, is not tolerant to water clogging in the soil (7). Oats are native to warm, sub-tropical regions and can manage well in poor soils (8) but they also require good water draining . The Experiments Germination Fifteen equally sized plastic containers (cylindrical in shape, approximately 8cm in diameter and 6cm in height) were filled with the same amount of soil. Five of them were allotted to each plant species; making sure to add the same amount of seeds in each segment (comparing to the same species, since the size of the beans and oats is much greater than the brown mustard seeds and would therefore be unreasonable to compare their numbers). Each of the containers was covered with cellophane of a different color (red, blue, yellow, green, or clear plastic wrap) and secured with a rubber band so that each species had a sample exposed to each different light color. They were watered with normal tap water, placed next to the same windowpane for a week and monitored every day. The cellophane secured with the rubber band created a seal that was too tight, preventing excess water from evaporating which overloaded the plants with water and deprived them of enough oxygen. Towards the end of the week, the plants were left covered by the cellophane, but unsecured by the rubber band so that the water was able to evaporate, to provide the dry mass of the samples, which were on average 0. 06g lighter than at the beginning of the week, when they were planted . The mass measured included the seeds, soil and plastic container. Even though an unknown type of fungus started growing in the containers because of the high humidity and warm temperature, some shoots were visible (Table 1). Cellophane ColorQualitative Data Red Some oat and mustard shoots, fungus growth Yellow Fungus growth, no shoots visible Green Oat and some mustard shoots visible, some fungus growth Blue Some oat and few mustard shoots, fungus growth Clear Fungus growth, no shoots visible These samples were discarded and a new method was devised: A cardboard egg container was cut into fifteen separate segments (for the five colors for each of the three species) which were to be used instead of the plastic containers to allow excess water to evaporate through the porous walls and bottom of the cardboard. These segments were then loosely filled in with cotton-wool. After the first experiment, where seeds drowned and fungus started to grow instead because of the excess of water, cotton seemed the best substitute for soil; it would allow for even dispersal of water, a lot of more light would be able to reach the seeds, it would be easier to observe the germination process, and since the cotton didn’t weigh practically anything, it would be easy to measure the change of plant mass on a scale. The segments were weighed once they had the cotton and seeds in them; their mass was noted down individually. A thin layer of cotton was placed on top of the seeds so they would retain moisture above them as well as below, but still allowing light to reach them. Then, the segments were watered with a handheld sprayer until the cotton was thoroughly moist and then were weighed again. To provide the different light coloring, one sample of each species was placed underneath a handmade cover fashioned out of bamboo and cellophane. These covers (Figure 1) provided the needed space for the plants to grow, free flow of air, and control of light shining on the plants. The cotton wool wasn’t a good substitute for soil since it retained little water and evaporated too quickly for the plants to take it in; it mostly bled into the cardboard, which, because of its porous nature, allowed for further evaporation of water. The results are shown in the following table: Color of CellophaneQualitative Data Red Few mustard shoots + very few oat shoots Yellow Very few mustard shoots Green Mustard shoots* + oat shoots ~4cm Blue Mustard shoots* + oat shoots ~3cm Clear Mustard shoots* + oat shoots ~6cm New cardboard segments were cut out and filled in with soil this time. Care was taken to add the same amount of soil (~ 4. 25g) and water (2. 0g) to each container at the beginning of the experiment. The following three days, the amount of water was altered from day to day to find the adequate amount of water that could be retained by the soil without too much bleeding into the cardboard container (since this would weaken its structure and remain unused by the plant); the conclusion was derived that the amount of water should be of the same mass as half of the soil in the container in order to maximize water intake by the plant: about 2. 5g. The results can be seen in Table 3 on the following page. Color of CellophaneQualitative Data Red Mustard sprouts* Yellow No growth Green Mustard sprouts * + oat shoots ~5cm Blue Mustard sprouts* + oat shoots ~8cm Clear Mustard sprouts* + oat shoots ~8cm Photosynthesis Rate The rate of photosynthesis was measured through the volume of oxygen produced in a set amount of time. To do this, six eudiometer tubes were wrapped with different color cellophane (one was left bare, to be the control) and filled with tap water. Next, six strands of Brazilian waterweeds were cut to the same size, each inserted into an eudiometer tube and then placed in a half filled beaker. The eudiometers were held with clamps on a stand and left next to wide windows to photosynthesize at their own rate. The oxygen produced by the plants floated to the surface creating bubbles that could then be measured and compared to each other. The sunlight provided was insufficient however, and the oxygen produced was too little to be measured accurately, but there were clear differences between the different samples; the waterweed in the red light was the one the produced most oxygen, followed by the green, then the blue, yellow, and clear. The control, the one without any cover, was the one that produced the least oxygen. After the experimentation, the data collected was reviewed to determine the most beneficial color for plant germination and photosynthesis rate. Taking the data from each week, the cellophane colors were arranged in order of effectiveness, to make it easier to compare the results (Table 4).

Ronald Reagan essays Ronald Wilson Reagan, known as "the great communicator," oversaw the largest peacetime and has had a significant impact ever since. In 1979, Reagan entered the race for the Republican nomination for president. He faced stiff competition but in May 1980, he received enough delegates to win the nomination. Reagan chose Bush as his running mate. After the convention, Reagan lost the large lead he had held over President Jimmy Carter, and they were often tied in the polls. Even though Reagan was criticized for being vague, his ability as a speaker helped him project a favorable image. His strong performance in a debate with Carter one week before the election was credited with winning over a large number of votes. Voters were troubled with inflation and by the year-long confinement of Americans in Iran.' Reagan promised to cut taxes and reduce spending, "while restoring Americas prestige abroad." Reagan received 50.7 % of the popular vote along with 489 electoral votes, while his opponent, Jimmy Carter received 41% of the popular vote with only 49 electoral votes. In the summer of 1984, Reagan campaigned for re-election. Supported by a vigorous economic recovery, Reagan turned his focus on certain key issues such as Balancing a Federal Budget, Central America, and The Strategic Defense Initiative. Polls indicated that Reagan appealed to many across borders such as age, class and even political party. "Reagan Democrats" turned away from the Democratic party as well as young voters who were historically pro-Democrat. Campaign ads for Reagan consisted of peaceful images of "Morning in America." Even with all the positive momentum toward re-election, there was still one thing that worried Reagans campaign managers, and that was Reagan himself. They feared that his image as a decisive and involved leader would fade under investigation, so Reagan avoided formal news conferences and many reporters. During the ...

Essay on Rape of Nanking notes

Essay on Rape of Nanking notes Essay on Rape of Nanking notes Japanese troops wanted to get rid of Nanking entirely to break the spirit of Chinese resistance. During the time of the genocide, the United States took the articles written in magazines such as Times, Readers Digest and New York Times doubtfully. The stories smuggled out of Nanking came across as too unrealistic to believe. There were many different ways of extermination for this genocide. One example is when the Japanese troops lined up the Chinese people along the banks of the Yangtze River, tied up their hands, and then shot them from behind with machine guns. Victims were also decapitated so that soldiers could use the heads as souvenirs. Another extermination method was to soak the Chinese in gasoline and burn them to death. The Japanese troops sometimes went door to door and some rapes of the Chinese even occurred in the public day and often in front of family members or spouses, some were even gang raped. The Japanese would rape the women and even the little children, treating them like dogs. They would also hit them with Bayonets and during the process the Japanese would proceed to kill some of them. Chinese prisoners were moved to the outskirts of Nanking and they were assembled for killing. Once Chinese soldiers were removed as a threat Japanese soldiers started to turn violence on public, most of which being women. The polarization for this Genocide had to do with the initial order to invade the previous capital of China. This was Japan’s way of showing the difference in ethnic groups. China was given the idea that they were separated very quickly. The Rape of Nanking is proven fact. This massacre has been denied by Japanese officials in an article written by CNN. During the massacre there were over 300,000 deaths

Direct and e marketing Essay Example | Topics and Well Written Essays - 1000 words

Direct and e marketing - Essay Example "The Internet is at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location" (1). Furthermore, some kind of businesses cannot manage without the Internet technologies and e-commerce. This paper will argue that it is impossible to imagine modern marketing technologies such as direct and e-marketing without effective data protection and privacy laws. 2. Data protection and privacy laws play a very important role for business development today and determine the future development of direct and e-marketing. "Direct marketing is intrusive, both in relation to the privacy of personal behaviour, and into the privacy of personal data. The degree of sensitivity varies greatly, depending on the person, the data and the context" (2). Data protection and privacy laws vary in different countries, but there are some significant similarities concerning the issue. In the United States some data protection acts have been adopted. "Actions such as the Fair Credit Reporting Act (FCRA), Fair and Accurate Credit Transactions Act of 2003 (FACT) and The Gramm-Leach-Bliley Act (GLB Act) have combined to create a relatively thorough protection of both financial data and personal information" (3). Financial data and personal information protection are of great importance especially while using such marketing methods as direct marketing and e-marketing. Nonpublic personal information term is precisely determined and concerns many aspects of financial data, customer and seller information. "Nonpublic personal information collected includes, but is not limited to, data from the consumer, the consumer's transactions with a financial institution or its affiliate, from nonaffiliated third parties about the consumer's transactions with them and from credit reporting agencies" (3). This information is protected with the data protection acts indicated above. European Union has also recently adopted data protection principles. The 8th Data Protection principle provides that "Personal data must not be transferred to a country or territory outside the European Economic Area unless that country or territory has an adequate level of protection for the rights and freedoms of data subjects" (4). The UK also adopt data protection acts, but "Many are also commenting that the UK has inadequately implemented the Electronic Privacy Directive (2002/58 /EC), resulting in too lenient a treatment of persons who send unsolicited commercial email ('spam') in the UK" (4). So, the UK data protection policy needs to be improved, as well as in France: "The French Data Protection Authority, Commission Nationale de L'Infortmatique et des Liberts ("CNIL"), has ruled that an email service provided by Rampell Software, a Florida-based company, is illegal, as it breaches French data protection law" (4). But later, in May 2003, the UK legislation changed:" The most controversial aspect of the legal changes is the new regulatory regime for email marketing.
